HOW MUSCLES GET THE ENERGY THEY NEED TO WORK 1) Muscle needs energy to contract and as stated previously the ‘universal energy currency’ of living systems is ATP (adenosine triphosphate). This is largely produced within mitochondria‚ organelles which are often referred to as the ‘powerhouse’ of the cell. The ATP that results is used to provide the power for the muscle fibres to contract. Contraction itself (i.e. actual shortening movement) occurs when a bond is broken between ATP and one of its

chapter Learning Objectives • Learn how our bodies change the food we eat into ATP to provide our muscles with the energy they need to move • Examine the three metabolic systems that generate ATP 2 Fuel for Exercise : Bioenergetics and Muscle Metabolism Terminology • Substrates – Fuel sources from which we make energy (adenosine triphosphate [ATP]) – Carbohydrate‚ fat‚ protein Measuring Energy Release • Can be calculated from heat produced • 1 calorie (cal) = heat energy required

Describe the preoperative and postoperative care of a client having PTCA/cardiac cath. What complications can occur post cardiac cath? The goal of PCI (percutaneous Transluminal intervention) is to open the blockage in the coronary artery. By opening the area that is blocked‚ it will help to reperfuse the myocardium. The faster this is done will help

Explain the structure and behaviour of water Similar to many other substances and liquids‚ water takes on numerous forms. It can either be solid as ice‚ gas as steam‚ and its usual liquid phase‚ water. Water molecules are electrically neutral and V-shaped with molecular formula H2O. In water‚ each hydrogen atom is bound to the oxygen atom by an electron pair‚ which is shared between them; this is known as covalent bonding. This process only uses two of the six

1. What do those numbers (130/87) mean? What do they relate to in the cardiac cycle? The numbers 130/87 is the blood pressure of the patient. The top number 130‚ is the reading that is received when the heart is in contraction and blood is pushed out of the heart into the rest of the body (this is called systole). The bottom number 87‚ is the reading when the heart is at it relaxed state and is being refilled with blood (this is called diastole.) 2. This deposition of platelets and fibrin can

sometimes that makes the child upset or angry. If you start them off young you can find out if they like it or not and it could save them a lot of time and also save you money. Also if you find out they don’t like the sport you have enough time to find out what else they might be interested in like another sport or getting involved in the community. Another reason is because starting them off young will build their strength and stamina It will also teach them the proper way to perform the actions safely

muscle contraction Introduction For a skeletal muscle fiber to contract‚ a stimulus must be applied to it. The stimulus is delivered by a nerve cell‚ or neuron. A neuron has a threadlike process called and axon that my run 91 cm or more to a muscle. A bundle of such fibers from man different neurons composes a nerve. A neuron that stimulates muscle tissue is called a motor neuron. The motor neuron branches into terminal structures called telodendria that come into close approximation with

Miracles Do Happen Sports and miracles kind of go hand in hand when athletes perform in games or practices. The Denver Broncos were down 24-0 at halftime against the San Diego Chargers‚ and they ending up winning 35-24 with 35 unanswered points. Many basketball games come down to the wire during March madness and many teams win by hitting buzzer beaters. For the USA hockey team‚ this miracle happened to swing their way. This special hockey team hit the biggest lottery numbers possible and took
